FLUSHING APPARATUS AND VALVE MECHANISHE THEREFOR.

Specification of Letters Patent.

Patented Oct. 30, 1917.

Application filed March 17,1917. Serial No. 155,382.

To all whom it may concern:

Be it known that I, HARRY G. TRAVER, a

citizen of the United States, and resident of tidgewood, in the countyof Bergen and State of New Jersey, have invented certain new and usefulImprovements in Flushing Apparatus and Valve Mechanism Therefor, ofwhich the following is a specification This invent-ion relates to waterflushing apparatus particularly adapted for flushing toilet bowls,urinals and the like in which the water for flushing purposes is underabnormal air pressureor greater'than ordinary atmospheric pressure, andit is the primary object of the invention to improve and simplify thegeneral construction of flushing apparatus of this character to cheapenthe cost of manufacture and at the same time increase the eficiencythereof.

It is a further object of the invention to provide a flushing apparatusin which manually operable means is provided to perform the initialfunctionof seating a valve to release the and in which the incomingwater to the reservoir operates to open the valve as it is unseated andwith the pressure of the water in the reservoir during the flushingoperation maintains the valve open, said incoming water also operatingto close the valve after the flushing operation and with the pressure ofthe water in the reservoir maintain the valve closed.

Another object of the invention relates to improved-valve mechanism tocontrol the flow of water from the reservoir and to improved meanstoactuate the valve.

lVith the foregoing objects and other objects and advantages hereinafterset forth I have shown in the drawing in side elevation, partly insection, a flushing apparatus illustrating an embodiment of myinvention.

The embodiment of my invention shown in the drawing comprises an airtight water reservoir or tank 1, only a portion of said reservoir beingshown, from the lower portion of which the water is discharged, asthrough an opening :2 at the bottom connected'to a closet bowl 3 througha pipe 4 connected at one end to the opening in the reservoir and at theother end to theinlet of a valve chamber 5, and a pipe 6 connected atopening or unflushing water,

one end to the outlet of the valve chamber and at the opposite end tothe closet bowl 3. The flow of water from the reservoir is controlled byvalve mechanism comprising the chamber 5 and opening lnto the valvechamber, or having a gravity seating valve a closing movement toward andan opening movement away from the outlet of the valve chamber. Thisvalve is in the nature of a flap valve comprising a disk 7 having a stemto engage in an opening in a carrier of slightly larger diameter thanthe stem by a nut threaded onto the stem whereby the disk may haverotative movement and a slight lateral movement relative to the axis ofthe stem to permit of the ready seating of the valve. The carrier ispivotally supported at the top of the valve chamber, as at 8, to swing.on a. horizontal axis. The valve is adapted to cooperate with an annularvalve seat 9 at the outlet of the valve chamber, this seat extending ina direction flightly inclined to the perpendicular there- )3 Access maybe .had to the valve chamber through anopening closed by a removableplug 10. r

The connection of the water pipe 4 with the valve chamber connection 1ssuch as facilitating the seating of the valve disk. 7

to lead the water into the valve chamber bei low the valve opposite thepivotal support of the valve and direct the water in a verticaldirection transverse to the valve seat and the opening valve tointersect the path of movement of the valve, for which purpose the pipe4 is substantially of U-shape as shown. The water inlet connection ofthe reservoir 1 with a water main'is also through the pipe 4 and .theopening 2 by a water inlet pipe 11 of less diameter than the pipe 4 andis connected to the pipe 4 adjacent the connection of the pipe 4 withthe valve chamber for a purpose to be hereinafter described. To drainthe entire water or any sediment from the reservoir and valve chamberthere is provided in the pipe 4, preferably in the bend thereof, a draincock 12. This cock may and closing movements of the also be utilized toadmit fresh air into the opening in the wall of the valve chambermaintain the valve in and a stuffing box 14, and is reciprocable in adirection in line with the valve. T he inner end of. the plunger ispreferably rounded and adapted to engage with an abutment or boss 15connected to or integral with the valve disk 7, the outer snr ace ofsaid abutment preferably being rounded to receive the shocks and wear ofthe plunger and protect the ground face adjacent to the periphery of thevalve disk 7. The plunger is manually operable from the exterior of thevalve chamber to unseat the valve by a hand lever pivotally supported atl6'having a pin and slot connection 1'? with the plunger, and having aweighted hand grip 18 whereby when the lever is manually operated toimpart movement to the plunger in one direction or into the valvechamber to unseat the valve and as it is released the weighted end ofthe lever will drop by gravity and automatically impart return movementto the plunger. 7

In operation the water from the main enters the reservoir compressingthe air therein until the air is compressed to a point when the airpressure on the water is equal to and will overcome the pressure of thewater entering from the main through the pipe ll. To perform theoperation of flushing the handle is lifted thereby moving too plungerinto the valve chamber, the epd of the plunger engaging the abutment loand moving the valve plate 7 from its seat. As soon as the valve isunseated the water in pipe at due to the pressure of the air in thereservoir 1 and the pressure of the water in the inlet pipe 11 will beforcibly directed in a vertical direction into the valve chamber tointersect the path of movement of the valve and will impinge against theouter face of the valve. or the side of the valve toward the outlet ofthe valve chamber. operating to lift the valve to the dotted lineposition adjacent the top of the valve chamber and so long as thepressure of the water from the reservoir and through the inlet pipe llis sufficient to maintain the valve in its raised position. As soon asthe air pressure in the reservoir is reduced whereby the pressure of thewater on the valve is not sutlicient to its raised position the valvewill drop by gravity and as the valve begins to drop the pressure of theflow of water through pipe '11 will be directed against the inner orrear face of the valve and operate to firmly seat the valve, and thevalve will be maintained seated by, the increasing pressure of the waterflowing into the reservoir. After inward movement has been imparted tothe plunger to unseat the valve the plunger operating lever is releasedwhen it will immediately drop and return the plunger to initialposition.

While the pressure or the incoming water ismaintained in such positioning through pipe 11 for flushing purposes,

thepressure of such water through pipe 11 must not be so great as to oercome the weight of the valve 7 and thereby prevent said alve fromfalling to its seat. I therefore provide avalve (shown in a general wayat 19) to control the flow and regulate the pressure of the waterthrough said pipe 11.
